PhD project:

Title: Experimental study of cooling solutions for PGC concepts

Short description: Pressure gain combustion concepts allow an increment of the efficiency of gas turbines while setting additional technological challenges. The isochoric heat addition obtained with the generation of rotating detonation waves in an annular combustion chamber determines critical heat loads which must be dissipated. This study will investigate the potential of different solutions initially considering low TRL configurations. The most promising will be selected and the performance will be investigated experimentally. The study will be developed in close connection with ESR10 which will carry out numerical simulation of the same configurations allowing for comparison of the results.
